Abstract

A seal plate assembly designed to quickly install and fully cover floor openings on a scaffold deck. The present invention includes at least one plate A and at least one bracket. The at least one plate A covers the floor opening, and the at least one bracket removably attaches the at least one plate A to the scaffold deck. Each plate A includes a slotted aperture designed to attach to the top of a bracket. This arrangement makes it easy to install, as the user simply slides the top of the bracket across the slotted aperture and connects the bottom of the bracket to a structural support, all without having to reach underneath and hold the bracket in place. In another embodiment, the present invention further includes a pair of plates B that are uniquely assembled to cover a remaining gap surrounding a fixed structure passing through the scaffold deck.

the at least one adjustable closeout being disposed on the top surface of the at least one plate A;

the pair of jaws slidably engaging with a protruding structure; and

the at least one adjustable closeout being capable of covering the floor opening between the at least one plate A and the protruding structure.

6 . The plate assembly as claimed in claim 5 comprising:

each of the first and second plates B being made out of a material that produces a magnetic field; and

the at least one adjustable closeout being magnetically attached to the at least one plate A.

7 . The plate assembly as claimed in claim 1 , wherein the plate A being rectilinear in shape.

8 . A plate assembly for covering floor openings on a scaffold deck, the plate assembly comprising:

at least one plate A;

at least one bracket;

the at least one plate A comprising a slotted aperture;

the slotted aperture being disposed on a top surface of the plate A;

the at least one plate A being positioned on top of a scaffold deck;

the at least one plate A covering a floor opening of the scaffold deck;

the at least one plate A being detachably mounted to the scaffold deck, via the at least one bracket;

the at least one bracket comprising a top end, a spanning portion, and a bottom end;

the spanning portion extending from the top end to the bottom end;

the top end being adapted to slidably engage with the slotted aperture of the at least one plate A;

the bottom end being adapted to detachably connect to the scaffold deck;

the bottom end further comprising a retainer hook;

the retainer hook being detachably connected to a structural support member of the scaffold deck;

the retainer hook being in the shape of an upward facing lip; and

the structural support member being a floorboard structure.

9 . The plate assembly as claimed in claim 8 comprising:

at least one adjustable closeout;

the at least one adjustable closeout comprising a first plate B, a second plate B, at least one bolt, and at least one nut;

the first plate B and the second plate B each comprising a cutout and at least one slotted aperture;

the cutout being disposed on an upper surface of each of the first and second plates B;

the at least one slotted aperture being disposed on a lower surface of each of the first and second plates B, traversing laterally;
